GAS DESTROYER Filed July 5, 1932 INVENTOR ATTOR N EY Patented Nov. 7,1933 UNITED STATES PATENT oFFlcE 2 Claims.

The invention relates to a gas destroyer for use with internalcombustion engines.

The primary object of the invention is the provision of a device of thischaracter, wherein carbon monoxide and other gases or fumes will beburned for destroying the same, thereby eliminating the possibility ofthe loss of life from inhalation-of such gases or fumes when operatingthe internal combustion engine.

Another object of the invention is the provision of a device of thischaracter, wherein the exhaust from an internal combustion engine, thatis, the gases present in the exhaust, will be burned for the consumptionthereof and thereby freeing such exhaust of obnoxious or dangerous gasesor fumes.

A further object of the invention is the provision of a device of thischaracter, which is simple in construction, thoroughly reliable, readilyand easily applied to the exhaust conduit of an internal combustionengine, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in thefeatures oi.' construction, combination and arrangement of parts as willbe hereinafter more fully described in detail, illustrated in theaccompanying drawing, which discloses the preferred embodiment of theinvention, and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary side elevation oi' an internal combustionengine showing the device constructed in accordance with the inventionapplied.

Figure 2 is an enlarged vertical longitudinal sectional view through thedevice.

Figure 3 is a sectional view on the line 3-3 of Figure 2 looking in thedirection of the arrows.

Similar reference characters indicate corre- 40 spending partsthroughout the several views in the drawing.

Referring to the drawing in detail, A designates generally a portion ofan internal combustion engine having the usual fuel intake manifold B 5and the exhaust manifold C respectively. In association with the exhaustmanifold C is the gas destroyer constituting the present invention andhereinafter fully described. f

The gas destroyer comprises a cylindrical cas- 50 ing including innerand outer walls 5 and 6 respectively, these being spaced frornfe'achother and 'within such space is an insulation or a fireproof lling 7,such for example, asbestos, the casing having a tapered end-8 this withthe other 55 encl being open. The said other endgfof, the cas,-

ing has tted thereto a cap or head 9, the same being telescopicallythreaded upon the casing while the tapered end carries a couplingextension 10 for connection with the outermost section 11 of an exhaustpipe.

The cap or head 9 has centrally formed therewith a coupling nipple 12which is joined through a fluid-tight joint 13 with the inner section 14of the exhaust pipe, the latter being connected with the exhaustmanifold C. This casing is in substitute for the conventional muiiler asemployed in the exhaust pipe o1' an internal combustion engine.

Carried by the cap or head concentrically with relation to the couplingnipple 12 integral there- 70 with is an exhaust or discharge nozzle 15having a contracted perforated free end 16, the same being centered withrelation to the casing 5 and projected a distance therein, while thelarger portion of said nozzle 15 is anchored or secured 75 v with thehead or cap 9.

The casing has fitted therein spaced screens 17 and 18 respectively, thelatter screen surrounding the contracted end portion 16 oi' the nozzle15 and rearwardly of the perforations therein and this screen 18 servesto divide the casing into a firing chamber 19 and a chamber 20, thelatter being concentric to the wider portion of the nozzle 15. The heador cap 9 has formed therein the concentrically arranged series of slots21 and perforations 22, the said slots establishing communication withthe interior of the nozzle 15 from the atmosphere, while theperforations 22 establish communication with the chamber 20 with theatmosphere. In other 90 Words, the slots 21 constitute primary air portsor entrances while the perforations 22 constitute secondary air ports orentrances. Mounted upon the coupling 12 of the head orcap 9 is an airintake regulator or shutter 23 which controls the slots 21 to regulatethe intake oi' air therethrough from the atmosphere.

The coupling nipple 12 projects slightly into the casing and thisprojected portion of said nipple carries a tubular member 24 havingformed therewith a Venturi Vnozzle 25, the major portion of said nozzlebeing perforated at 25 `and projected into the member 24 which isspa'cedfv fromandpconcentric thereof, the Venturi tip2ii openinghintothe nozzle 15.1l

The casing of thedevicelntermediatejof,its l .y ends and "at the'uppermost portion thereof is .f countersunk at 27 with an.4 opening foraccom-f .l 'molating'fa spark plug 28 which is arrange'diin the-ignitionsystem of the internal combustion 110 engine. This spark plug 28 whensparking ignites the gases and fumes let into the casing through theVenturi tip 26 and dischargenozzle 15, the gases or fumes being renderedcornbustible by the mixing of air admitted through the slots 2l andapertures 22 so that the exhaust from the manifold C of the engine Awill have obnoxious and dangerous gases eliminated therefrom prior tothe discharge of the exhaust through the outer section 11 of the exhaustpipe. It is of course understood that the exhaust from the manifold Cunder pressure will be forced into the device for the burning thereof inthe sparking of the plug 28 which ignites gaseous fluid for destroyingthe gases or fumes during the working of the internal combustion engineprior to the discharge of the exhaust to the atmosphere through theexhaust pipe connected with the manifold C of said engine.

What is claimed isz- 1. A gas destroyer of the kind described comprisinga cylindrical casing having inner and outer walls spacedv from eachother, an insulating material between the said Walls, means for couplingone end of the casing to an exhaust manifold of an internal combustionengine, a coupling nipple included in said coupling and projectedslightly into the casing, a tubular inember fitted on said nipple andhaving a Venturi nozzle, the said nozzle being perforated for a majorportion thereof, spaced screens fitted interiorly of the casing, anexhaust nozzle related to the coupling nipple and having a contractedperforated free end extended through one of the screens, the exhaustnozzle being concentrically disposed with respect to the Venturi nozzle,a Venturi tip on said Venturi nozzle and in confronting relation to thecontracted end of the exhaust nozzle, the said coupled end of the casinghaving primary and secondary air ports, and an adjustable shutterregulating said prrnary ports.

2. A gas destroyer of the kind described cornprising a cylindricalcasing having inner and outer walls spaced from each other, aninsulating material between the said Walls, means for coupling one endof the casing to an exhaust manifold of an internal combustion engine, acoupling nipple included in said coupling and projected slightly intothe casing, a tubular member fitted on said nipple and having a Venturinozzle, the said nozzle being perforated for a major portion thereof,spaced screens tted interiorly of the casing, an exhaust nozzle relatedto the coupling nipple and having a contracted perforated free endextended through one of the screens, the exhaust nozzle beingconcentrically disposed with respect to the Venturi nozzle, a Venturitip on said Venturi nozzle and in confronting relation to the contractedend of the exhaust nozzle, the said coupled end of the casing havingprimary and secondary air ports, an adjustable shutter regulating saidprimary ports, and an ignition device within said casing adjacent to thereduced perforated end of the exhaust nozzle.
